WATER-PURIFYING APPARATUS FOR STEAM-BBTLERS.

1 Specification of Letters Patent. Patented 1\Ia,1'. 2S, 1911.

Application filed March 20, 1908. Serial No. 422,258.

and I do hereby declare the following to be,

a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i i

The present invention relates to a device consisting of the combinationof a water purifying apparatus with one or more steam boilers directly, so that the boiler water can circulate between the boilers and the purifier and in which there is supplied to the purifier besides the water delivered to it from the boilers also fresh water. By this deviceI am enabled to preventtlie formation of calcareous deposit in the boiler and also the formation of foam..

In the accompanying drawing-the invention is illustrated diagrammatically. To the discharge cocks, at, at the bottom of the boilers, c, which leads to a point at the lower portion of the purifier, (I, as shown. The impure water from the bottom of the boilers is thus conveyed to the bottom portion of the interior of the purifier, said purifier being closed at its top and having a vertical sleeve, d, extending'centrallyfrom the cover to a point in the interior near the bottom. The

connecting pipe, 0, extends through this sleeve, as shown and discharges below its lower edge. Above this discharge and in the upper part of the purifier is arranged a horizontal filtering layer, f, and above the sameis arranged the discharge, g, for the purified water, said discharge leading to a reservoir from which the boilers are supplied in a manner well-known. water pipe, e, delivers fresh water to the purifier, said pipe discharging into the sleeve, (1, as shown. Sufiicient water is.

thereby added to supply the loss-of water by evaporation in the boilers'. At the bottom of the purifier there is provided a blowofl' valve, 72,, through which the sediment and dirt separated fromthe water can be disb, there is connected the pipe A fresh charged from time to time. Closingor dividing valves as required may be arranged in the pipe 0. By this arrangement the water from the bottom of the boiler, that is at. the point where it is the most charged with dirt, sediment and impurities, is con-- PATENT OFFICE.

veyed into the purifier where, it is forced to pass upwardly through the filtering materia'l and under conditions whereby a portion of the impurities are deposited in the bottom .of the purifier, before they reach the filter, and where no deposit of sediment and impurities on the filter and a consequent clogging'of the same can arise.

lVhat I claim and desire to secure by Letters Patent is: I

1. A water purifier havinga filter in its upper portion, in combination with a ver- 'tical sleeve extending from they cover of the I purifier to a point in the interior near its bottom, and a feed pipe for water to be purified arranged with said sleeve and arranged to discharge below the lower edge of the 'sleeve.

2. A- water purifier having an interior vertical sleeve open at top and bottom extending to the lower portion of the purlfier,

in combination with a filtering layer in; said i ,purifier, and occupying the space between the sleeve and the walls of the purlfier, and in communication with the upper and lower portionsof said space, a pipe for feeding water to be purified and arranged to deliver the same below the lower; edge of said sleeve.

3. A water purifier having an interior.

verticalsleeve, open at top and bottom, ex-

tending'from the top of same tothe lower portion of the interior of the same, in combination with a filtering layer 1n said purifier arranged in the space between the sleeve and the walls of the purifier, a feedpipe for water .to be purified arranged 'w1tl11n said sleeve and passingto a point below the bottom edge of the same, and a second plpe for delivering freshwater lnto the sleeve.

In testimony whereof I hereunto afiix my signature in the presence of two w1tnesses.
